How do you know it's a <insert vendor> field engineer trying to fix a
flat tire? He keeps swapping tires till he finds the flat one...
Make sure your testing procedure *really* tests the actual spare circuit,
not something else's representation of one. I know one poor soul who
wrote software to monitor-via-ping the other end of a point-to-point,
then watched in horror as a co-worker accidentally removed the entire
DSU from the rack, unwilling to say "Wait, that's the wrong one" because
the monitor hadn't burped an error.
Guess who's network was basically a triangle? ;)
